Recently learned about an intriguing financial technology innovation - PayFi Stack. This framework, developed by Huma Finance, divides the financial system into six layers, creating an efficient, secure, and transparent payment ecosystem.

The core advantage of PayFi Stack lies in its multi-layer architecture. The transaction layer leverages Solana's high-speed processing capability, achieving an astonishing 400 milliseconds transaction speed. The currency layer uses stablecoins like USDC and PYUSD to ensure the stability of funds. In terms of security, the custody layer introduces well-known service providers such as Fireblocks and Cobo, greatly enhancing the safety of funds. The compliance layer effectively prevents money laundering and other illegal activities through tools like Elliptic.

It is particularly worth mentioning the financing layer and the application layer. The financing layer can quickly convert invoices into cash, addressing urgent needs for many businesses. The application layer supports cross-border payment services such as Arf, greatly facilitating international trade.

Since its launch in July 2024, PayFi Stack has processed $38 billion in transaction volume, proving its practicality and reliability. The most attractive feature of this system is that it significantly shortens the time for cross-border payments, reducing it from the traditional 3-5 days to nearly real-time, while also significantly lowering transaction fees.

Huma Finance's collaboration with industry giants like Solana and Circle signifies its ambition to enter the $16 trillion payment market. This innovation is not only a technological breakthrough but also brings tangible economic benefits to ordinary users and businesses.

With the continuous development of Web3 finance, innovations like PayFi Stack are reshaping our perception of financial services. It not only improves efficiency and reduces costs but also provides users with more opportunities to participate and benefit. This transformation could have a profound impact on the traditional financial system, pushing the entire industry towards a more open, efficient, and inclusive direction.
